SIDNEY DA'ITNEB JACOBSON, OF NEW YORK, N. Y.

ANTISKIDDING DEVICE.

Application filed March 2, 1921.

I '0 all whom it may concern Be it known that I, SIDNEY DATTNER JACOBSON, residing at New York, in the county and State of New York, have in vented certain new and useful Improvements in Anti-skidding Devices, of which the following is a specification.

This invention relates to anti-skidding devices, and more particularly to an antiskidding device adapted for use upon the wheels of motor driven vehicles, such as automobiles, trucks and the like.

One of the objects of the invention is to provide a new and improved anti-skidding device of the Weed chain type, wherein the cross-links are readily removable for the purpose of replacement when worn or broken, and of such construction that there is no likelihood of any section of crosslinks becoming accidently detached from the links of the circumferentially disposed chains to which the cross-link sections are attached.

Another object of the invention is to provide a new and improved hook for attaching the cross-links to the circumferentially disposed links of the tire chain.

Other objects and aims of the invention, more or less specific than those referred to above, will be in part obvious and in part pointed out in the course of the following description of the elements, combinations, arrangements of parts and applications of principles, constituting the invention; and the scope of protection contemplated will be indicated in the appended claims.

In the accompanying drawing, wherein I have illustrated a preferred form of embodiment of my invention:

Figure 1 is a plan view of a portion of an anti-skidding chain, showing my improved cross-link construction connected therewith.

Figure 2 is a sectional view through my improved hook; and

Figure 8 is a perspective View of said hook. I

Referring now to the drawings, wherein similar reference characters refer to similar parts throughout the views thereof, the reference numerals 1 and 2 denote the circumferentially disposed chains, the same being the well known Weed type, and 3 indicates one of the cross-chains, the same being extended between the side chains as shown.

4. indicates one of the devices adapted to attach the ends of the cross-chains to the Serial No. 449,053.

side chains, said device being formed of wire bent into U-shape, as shown, the U-bend 5 being adapted to be interlocked with the end link of the cross-chain. The free ends of the device 4 are bent upwardly, as at 6, and rearwardly, as at 7, said free ends lying in parallel relation, as shown, and being inclined slightly downwardly as they approach their outer ends.

The end surface of each of the ends 7 of the device 4: are cut away, as at 8, to receive shouldered ends 9'0f a keeper 10, said keeper being made of a fiat strip of metal bent into the form shown, and said keeper having flanged portions 11 and 12, which are bent around the legs 13 and let of said device 4. If desired, these flanges 11 and 12 may be spot welded to the respective legs of the device upon which they are mounted, or they may be riveted thereon, it being desirable to fasten the parts together, so as to prevent any longitudinal displacement.

The outer end of the keeper 10 is provided with a tongue 15, which is located between the free ends 7 of the legs 13 and 14, said tongue being erected between the shoulders 8.

Figure l of the drawings shows the manner in which the hooked ends of the device 4 are snapped about the opposite links of the side chains.

It will accordingly be seen that I have provided a device well adapted to attain, among others, all the aims and objects above pointed out, in a simple and eflicient manner. The construction of the hook device which is employed to connect the cross-chains to the side chains is such as to make it impossible for any accidental disengagement of the cross-chains from said side chains, inasmuch as the tongue which extends between the ends 7 of the legs 13 and 14 prevents the side links from connecting between the keeper 10 and the hook ends 7.

As many changes could be made in this construction without departing from the scope of the following claim, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative only and not in a limiting sense.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

In a device of the character described, the combination with a pair of side chains and a cross-chain, of a member adapted for dea tongue projecting from it and arranged between the legs of the U-shaped member and curved upwardly to prevent the displacement of the said keeper sidewise.

In testimony whereof, I aflix my signature 15 in the presence of two witnesses. 1
